Abstract
X-ray time modulation was investigated in the total external reflection conditions in the process of x-ray diffraction on the surface of the YX cut of a LiNbO3 crystal modulated by the rectangular pulses of the surface acoustic waves. It is shown that the period and the width of the x-ray pulses are determined by the period and the width of the rectangular surface acoustic waves pulses. Through the use of surface acoustic waves pulses it is possible to form the x-ray pulses with special forms of x-ray beam control, for investigation of time modulated process in microelectronic materials, and also for x-ray/acoustic microscopy, which can be based on thermal or thermoelastically generated acoustic waves by x-ray pulses at the depth of x-ray penetration in investigating materials. These experiments have been made at CNRS (Grenoble, France) using a rotating copper anode.
